Better Visual Indicator for Lingering Blades (+MTX)

Default Ethereal Knives leave a Lingering Blade that is relatively easy to find when there isn't much clutter. However, with MTX and bodies and ground effects, it's difficult to know where to click for Blade Blast.

Lack of any real identifying effects or visual indicator is made substantially worse when using an MTX like Ebony Ethereal Knives. Most maps are already dark or used dark colors, rendering the black lingering blades essentially invisible.

Potentially making the lingering blades larger or adding a ground aura/pulse around the blades similar to the Abyss visual effects could help not only make the skill effect look better and clearer, but also help functionality.
